Basic Tank Maintenance Tips

Keeping your HPA tank in good condition helps maintain consistent performance and extends the life of your regulator and internal components.

• Always degas your tank before servicing any regulator or internal components
• Check for leaks regularly around the regulator, fill nipple, and burst disc
• Keep threads and fill areas clean to prevent dirt from entering the system
• Replace worn O-rings and seals as part of routine maintenance
• Store tanks in a cool, dry place away from extreme heat
• Follow hydro test requirements for your tank type and location
  
• Ensure set screws are tight to avoid bonnet from coming loose when removing from marker
  

Pro Tip: If your tank starts leaking or output becomes inconsistent, a rebuild kit is often the fastest and most cost-effective way to restore performance.
